Hurrah! The laser cut acrylic for my NIXIE tube clock casearrived
this morning, and amazingly all the parts fit together nicely. The screw
holes even matched up with the PCBs!

I'm pretty happy with how this turned out, and I can finally say the
nixie clock project is finished. I definitely learned a lot for the next
clock - like use the RTC with an onboard crystal! I'm thinking of
perhaps making a wordclock.

You can check out the Inkscape files I sent to Ponoko for manufacture
here (they are released under CC BY-SA 3.0 if you are interested).

In unrelated news, design on revision four of my motor controller is
nearing completion, so hopefully the thing will be flying soon!
